I just did the Screen mod for my Lynx model I and LOVE IT! The screen is great! It is bright and clear! The VGA output is great too! I'll be honest though, If you don't have some serious soldering skills, you are far better off sending your unit off to McWill to do the mod for you! I've been doing electronics repair my whole life but still found this mod challenging!
If you do undertake this yourself and have a Lynx model I, I advise you to take a vga cable, cut it open, and use the wires for this project. VGA cables have very thin wires and you will need thin to solder the wires on pins 14, 16, 18, 31, 36, 39, 41 and 58. It also would not hurt to have some solder braid and a solder sucker too.
As far as the price is concerned, anything great costs a lot! It takes time and skill to develop these things. He should be rewarded for his efforts! You don't do a mod project like this cheaply. It is an expensive undertaking, but worth it. In the end you have something very special!
Hats off to McWill for such an amazing mod!
Below are some pictures I took. The pictures really don't to it justice though. It looks even better in person.
I also have a video that I took. You can view it here:
